# Preview a certificate template

`POST https://api.cademi.com.br/api/v3/products/{product_id}/certificate-template/previews`

Operation ID: `certificates.template.previews.create` · API v3

Renders a sample certificate from the product's current certificate template, using placeholder data.

A preview is not an issued certificate: it does not appear in certificate listings or reports and cannot be verified through public validation. The response does not include a `file_id`; use `pdf_url` to access the rendered PDF.

Templates of replicated products cannot be previewed.

Required permissions: `certificates.preview`.
